T0 f/Z yunioni it may Gomera.'

Be it known that 1, S'racy B. HASEIQTINE,

a citizen of the United States, residing' at Chicago, in the county of Cook and State of Illinois. have. invented a certain new and useful Improvement in Draft-Yokes for Railway-Cars, of which the following is a full. clear. concise, and exact description, reference being had to the accompanying drawings. forming a part of this speciii cation.

My invention relates to improvements in draft yokes for railway cars.

The object of my invention is to provide a draft yoke of simple construction and eiiicient operation, and one in which the draw bar'may be readily removed therefrom, and in which the draft gear may be readily dismounted. y

In the drawings forming a part of this specification-Figure 1 is a plan view part] in horizontal section on line 1 1 of Fig. Q of a. draft yoke embodying my invention; Fig. 2 is a central vertical longitudinal see tion on line 2 2 of Fig. 1 showing'thc parts of the yoke in assembled position; Fig. 3 is a vertical longitudinal section showing the parts ,thereof detached from coupler. Fig. 4 is a cross section taken on line of Fig 2; Fig. 5 is a. rear end elevation taken atline 5 5 of Fig. 2; Figs. G and 7 represent a modification, F ig. 6 being-a verf tical longitudinal section of the rear end of a modified form of the draft yoke taken on the line 6 6 of Fig. 7,'and Fig. 7 a rear elevation thereof taken at line 7 7 of Fig. 6.

Referring to the drawings the numeral 8 represents a draw bar, the rear end thereof only being shown in the drawing; 9 theI butt of said draw bar forwardly provided with the shoulders 10, 10, the said draw bar being of a standard well known type.

The numeral 11 represents a draft yoke lcomprisingr three main portions, to-wit: an

`tpper arm 12, a lower arm 13, anda rear vconnecting member 14. The yoke 11 is forwardly provided with a hollow box-like member 15, which is preferably integral with the upper limb 12 of the yoke, rand bears a transverse inwardly turned lug 16 at its forward end adapted to engage with the u per shoulder 10 of the draw bar. The said allow box-like memberl is adapted to receive the draw bar, and also to receive the Specification of Letters Patent.l

forward end of the lower limb 13 ofthe yoke, the said lower limb being provided with a transverse inturned gib 17 adapted to engage with the lower shoulder 10 of the draw bar, and also provided withv suitable means, preferably the lugs 18, 18, downwardly extended from the forward end thereof, and engaging the lower member 19 of the hollow box-.like member 15 to hold the forward end of the said lower limban engagement with the draw bar. The rear end of the upper limb of the yoke is adapted to engage with, preferably by pivotal means, the connecting member 14. The connect-ing member 14 comprises a. pair of arms Q0, Q0 engaging either side of the rear end of the upper limb of the yoke, and pivoted thereto by means of the pin 21 passing through said arms and through the slot 2:2 in said upper limb.

ln preferable construction the rear end. of the upper limb 12 is narrowed, as shown in Fig, 1 of the drawings, and the said narrow portion of thicker vertical dimensions, as shown at the numeral 23 of Figs? of the drawings. so as to permit the engagement of the arms QU. 20 therewith without widening' the yoke in its entirety, and without widening the upper limb thereof.

The connceting` member 14 is provided between thc armi" 2O with a web 24 connecting the said arms 20. and preferably integral therewith, the same formingr iu preferable onstruction at its upper end a. shoulder 25 to engage against the shoulder 26 formed by the depending portion 27 of the rear end of the upper limb 1:13 of the yoke. vThe said perforation is sufficiently extended longitudinally to permit the connecting mem lier 1l to be swung rearwardly upon thi pivot'Ql when the said pivot is moved to the 'forward end of the perforation 22 in the limb 12. .lt its lower end the connecting member 14 is provided with a key wav formed preferably by the transverse slots 30. 30 in the arms :'20, QG. A longitudinal re.- cess 31 is provided in the lower end of thc. connecting member 14 to receive the rear ond of the lower member 15 of the yoke, the said lower limb being provided with a transverse slot 32 to .receive the key 33, .fhich extends through said slot and through the perforations 30 in the connecting member 14. The lower member 19 of the hollow boxlike member 15 is provided with afperfo ration of suiicient dimensions to receive therethrough one of the lugs18 with which the lower limb is provided.

ln disconnecting the draw bar 4trom the yoke, the key 33 is first removed after which the two arms or members of the yoke 12 and 1. are moved longitudinally relatively to each other, either by moving the member 12 forwardly or by moving the member 13 rearwardly until the front lug 18 drops into the perforation 3 5. This permits the arms of the yoke to separate a sufficient distance to give clearance for the abutments or snoiilu ders 10 on the draw bar, whereupon the latter may be taken ont. ln taking ont the draft gear without taking out the draw bar, the key 3? will be removed as above described, after which the lower member O the yoke l?. will be pushed forwardly until the lugs i8, 18 have passed out beyond the plate 19, whereupon the-member 13 will dro down and may be pulled still farther and tilted downwardly sufficiently to provide clearance l'or removing the gear.

As shown most clearly in'Fig. l, the rear inner walls 50 of the gibs or lugs 16 and 17l on the yoke members, are curved to permit the draw bar to swing radially relatively to the yoke, it being understood that the inner end of the draw bar is less in width than the distance between the vertical walls of the nox-like member 15 as shown most clearly in Fig. 4.

In the' modification illustrated in Figs. 6 and 7f`oi the drawings the upper limb'36 of the yoke. is pivotally connected with a connecting member 38, the said connecting vmember 38 being provided at itsllower end with a longitudinal recess 39 to receive the rel il' end of the lower limb 40 'of the yoke, the saiddower limb being provided with atransverse slot 4l, and the connecting member having transverse slots 42, 42 registering therewith for the passage of 'thckey 43.

which secures the lower I imb 40 to the coni' nccting member 38. Preferably a cotterfl is employed to secure the key 43 against` accidental ddisplacement. At its rear end n'pper limb 36 ofthe yoke is laterally pr0- yided with bearing facesfl, 45 to receive the intiirned lugs 4,6, 4G with which the upper end of the ci'innecting' memberS is provided, thus pirotally engaging the said connecting member 38 to the upper limb 36, the said connecting member being also Aprovided with a shoulder 47 engaging against the shoulder- 48' formcd by the depending portion'f) at the rear end ot' thc upper limb 36 oi' the yoke to hold the connecting member and the upper limb in firm eoengagement. The modification illus'` 'atcdJ'clates only to the rear end of the yoke, the other parts of the yoke being connecting Vmember being pivotally connect-v ed to one of said limbs, and adapted to be keyed to the other of said limbs.

In a draft yoke for railway cars, upper and lower limbs adapted to engage a draw bar, a 'rear connecting member for said limbs and a key, the rear connecting member being keyed to one of said limbs and secured to the other of said limbs., f cnnnectng member being slidingly pivoted to s irl last mentioned limb when disengaged Vtrom the key.

3. In a draft yoke for railway cars, the combination with a limb having a. hollow box-like member to receive the draw bar and a detachable limb engaging the draw bar. of a'connectiug member for said limbs and a key, the connecting member being swingingly mounted on one of limbs and keyed to the other limb. .l

fl. In a. draft yoke for railway cars, a pair of limbs adapted to engage a draw bar at theirone end and a member to connect said limbs at their other end, and a key, the said connecting member being swingingly mounted on one of said limbs, and having a recess to receive the other of said limbs, the key being adapted .to secure said limb Within. the

recess.

5. Ina draft yoke for railway cars, a'pair of limbs, a third member connecting said limbs at the rear vends thereof, and a removable transversely extending key engaging said member'a'nd one only of said limbs forl 'tioned limb being provided with a lug, and

the band-shaped member being provided with an aperture to receive saidflng on dis' engagement of the limbs of the yoke from STACY B. HASELTINE.
